Abstract

The invention discloses a water-cooling water chilling unit and an energy-saving operation control method thereof. The method comprises the following steps that the chilled water outlet water temperature of the water-cooling water chilling unit is detected in real time; when the chilled water outlet water temperature of the water-cooling water chilling unit is lower than a first preset temperature, the water-cooling water chilling unit is controlled to execute an unloading action, and the current load of the water-cooling water chilling unit is judged; and if the current load of the water-cooling water chilling unit is less than or equal to the minimum allowable operation load of the water-cooling water chilling unit, a compressor in the water-cooling water chilling unit is controlled to be stopped, and a water-cooling water pump and a cooling tower fan in the water-cooling water chilling unit are shut down. According to the method, frequent alarming and shutdown of the water-cooling water chilling unit can be effectively avoided; the reliability of the water-cooling water chilling unit is improved, and the service life of the water-cooling water chilling unit is prolonged. Meanwhile, the energy resource waste is reduced, the user application cost is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy-saving operation control method of a water-cooled chiller and a water-cooled chiller. Background technique [0002] Usually, during the operation of the air conditioner, if the user load is relatively small, it will often occur that the chilled water outlet temperature is lower than the target temperature set by the user. [0003] In related technologies, when the chilled water outlet temperature is lower than the target temperature set by the user and the unit has reached the minimum load, the unit is controlled to operate at the minimum load until the unit fails to protect and shut down. This method will cause frequent fault alarms and shutdowns of the unit, greatly reducing user experience and causing energy waste. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain ...
